I'm thinking about making the transition from PC to the new imac but have a few questions. 1) Noise: I recently returned a T61 because it was too noisy. The fans cycled on and off every 2 minutes, even during Internet usage, word processing, etc (hardly processor intensive apps). Lenovo had billed it as the coolest, quietest laptop but my experience was anything but that. How quiet, exactly, are the new aluminum imacs? 2) Heat: I looked at the 20" and 24" models in Best Buy. As I ran my hand around the edges to see how hot they were, the 20" model was warm but the 24" model seemed to be inordinately more so. The store was way too noisy to see how the fan was trying to compensate but I have concerns about machines that run that warmly in terms of their longevity. I've steered clear of slimline pc's in the past due to mitigated ability to dissipate heat. 3) Windows: I am not a Windows addict and I will do anything to not use Vista. However, I like XP just fine and I am a big fan of Office 2007. The office 08 version for macs doesn't do a whole lot for me, so I am thinking of partitioning the drive and running XP too. Has anyone had any experience with this? Does it run smoothly? 4) TV: Several PC's that I am looking at allow you to hook up cable and watch TV. Does the imac allow this? 5) Processor: Intel has released their quad core processor now. Any idea if/when it will be in the imacs? Sorry for all the questions, thanks for your assistance.
